  private static final String TAG = "Chilkat";

  // Called when the activity is first created.

    //  This example requires the Chilkat API to have been previously unlocked.

    //  This example simulates this FORM:
    //  <form action="echoPost.asp" method="post">
    //  First name: <input type="text" name="firstName"><br />
    //  Last name: <input type="text" name="lastName"><br />
    //  <input type="submit" value="Submit">
    //  </form>
    //  The online FORM is found at this URL:
    //  https://www.chilkatsoft.com/simpleForm.html

    //  Build an HTTP POST Request:
    req.put_HttpVerb("POST");

    //  The FORM target is http://www.chilkatsoft.com/processPost.asp
    //  An easy way of filling out most of the HTTP request object
    //  is to call SetFromUrl:
    req.SetFromUrl("https://www.chilkatsoft.com/echoPost.asp");

    //  Send form params using application/x-www-form-urlencoded
    req.put_ContentType("application/x-www-form-urlencoded");

    //  The only remaining task is to add the params to the
    //  HTTP request object:
    req.AddParam("firstName","Matt");
    req.AddParam("lastName","Jones");

    //  Send the HTTP POST and get the response.
    //  The POST is being sent to chilkatsoft.com, on port 443 (using TLS)
    String domain = "chilkatsoft.com";
    int port = 443;
    boolean tls = true;

    //  The HTTP POST is sent here:
    CkHttpResponse resp = http.SynchronousRequest(domain,port,tls,req);
    if (http.get_LastMethodSuccess() == false) {
        Log.i(TAG, http.lastErrorText());
        return;
        }

    //  Display the HTML source of the page returned.
    Log.i(TAG, resp.bodyStr());

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
